Current Output

Polycrystalline silicon array, fixed ground-mount.

The silicon crystals that form polycrystalline panels are manufactured through a different process to monocrystalline technologies. The efficiency of crystalline panels continues to increase, as the comparison of recent-generation polycrystalline panels to earlier models shows.

These WINAICO panels offer a positive tolerance of +5% on the rated output. This means the panel may produce slightly more than the rated 240 Watts under test conditions, but not less. The variation in panel output is important because when panels are connected in series their output is limited to the output of the lowest connected panel.

WINAICO panels have also been made with materials that reduce the amount of leakage current – small currents that flow from the photovoltaic cell through the mounting materials – that can reduce the panel’s output over its lifetime.

This array is installed on ground mounted concrete ballasted Schletter array frame.

Notes on the Data

  1. Monitoring Interruption for UPS Battery Replacement

    The disconnection and re-connection of the solar arrays and weather station equipment while a new site connection was being established prompted the already flattening UPS batteries which power the site’s energy meters to fail and require immediate replacement. Data recording was affected from approximately 2.30pm ACST, Monday 10 July to 4.00pm, Wednesday 12 July.

  2. Partial System Outage

    One of the major switchboards at the DKASC lost power yesterday 01/12/2016 at ~11:00 am. This isolated and shutdown array sites 23 through to 37 inclusive. The switchboard was re-energised at ~16:30 today (02/12/2016) and is again operating normally. Data for this period for these sites is lost.

  3. Site 34: Temporary Shutdown

    Site 34 was temporarily shutdown on the 11th May 2016 from ~ 10:00 am to 6:00 pm. This was to de-energize the underground cable feeding the site to allow for safe trenching and augering work on neighbouring sites.

  4. System Outage - Sites 4, 5, 17, 20, 22, 34 and 35

    On the 5th June 2015, A Friday before a long weekend, seven individual PV systems at the DKASC were switched off by unknown persons and for unknown reasons. The outage was not noted until the following Tuesday when O&M staff returned to work and found the main circuit breakers for sites 4, 5, 17, 20, 22, 34 & 35. turned off. These systems were all turned back on again on the 9th March when the problem was detected.

  5. Site 34: System Fault

    In late June 2013 an issue was detected with Site 34 the Winaico system. For much of the month of June the Winaico system inverter was shutting itself on and off intermittently. After much investigation the problem was sourced to a loose neutral wire in one the DKASC switchboards which was causing an intermittent floating neutral and a subsequent voltage rise on the phase that the Winaico system is connected to. Other systems at the DKASC were also effected by this probelm but to a much lesser extent. These included all sites 23-39. The problem is now resolved and all data from 3rd July 2013 can be considered accurate. The system data for the Winaico system for June 2013 is not representative of the true performance of the Winaico system.
